Port length decision... need assistance
Ok, I will have 7.5 net after subs, bracing, and port displacement (guestimating roughly 1 cf).
The port i am using will be 8" x 16" and i am trying to determine the length. I have tried carstereo.com's calculator, but im not sure why it gives different lengths depeding of if this is a slot port. It can very easily be, or it can be a square port in the middle of the box, id rather it be slot though for extra bracing.
I am coming up with a lenght of 14.51" for slot, 22.51 for not.
can somebody help me determine the length:
7.5 cubes, 8"x16" x ??? slot port, 38 hz
